Abstract BackgroundAsymptomatic bacteriuria can be a cause of adverse pregnancy and neonatal outcomes if undetected and untreated. Pregnant women are usually routinely screened with urine cultures at antenatal booking. However, the exact burden of asymptomatic bacteriuria in Nigeria is unknown. Our protocol is aimed at determining the pooled prevalence of asymptomatic bacteriuria amongst Nigerian pregnant women as well as the associated risk factors and pregnancy outcomes.MethodsNine databases: PubMed, African Journal Online, Google Scholar, Cochrane Library, CINAHL, Embase, ResearchGate, Scopus, and Web of Science will be searched using a search strategy that is developed by combinations of MeSH terms, keywords, text words, and entry terms. Only observational studies published or retrievable in the English Language will be included. Studies must be conducted in Nigeria. The primary measurable outcome of this study is the prevalence of asymptomatic bacteriuria in pregnant women. Identified studies will be screened, selected, and deduplicated in DistillerSR. Data items will be extracted into predefined forms in the DistillerSR. Reports including Prisma flow chart, quality scores, risk of bias, and study outcomes will be generated in DistillerSR. Extracted data items will be exported into the Comprehensive Meta-analysis Software version 3 for quantitative analysis. Methodological, clinical, and statistical heterogeneity will be assessed for all the studies. Publication bias will be assessed using Funnel plots. There will be a subgroup analysis of pooled prevalence using categorical variables. The primary outcome will be expressed in pooled prevalence, standard error, variance, and 95% CI of variance. Quantitative risk factors and pregnancy outcomes will be used used for meta-regression. The reporting of the systematic review and meta-analysis will be according to PRISMA 2015 Statement.DiscussionThe pooled prevalence of asymptomatic bacteriuria in Nigeria will be examined in relation to associated risk factors and pregnancy outcomes. The study will be published in a peer-reviewed scientific journal.Trial Registration NumberThis protocol is registered with the Prospective Register of Systematic Reviews (PROSPERO) with registration number CRD42020213810

ObjectiveThe purpose of this paper is to perform a systematic review and meta-analysis in order to summarise the prevalence of diabetes and pre-diabetes and their associated risk factors in Bangladesh.DesignSystematic review and meta-analysis.ParticipantsGeneral population of Bangladesh.Data sourcesPubMed, Medline, Embase, Bangladesh Journals Online, Science Direct, Scopus, Cochrane Library and Web of Science were used to search for studies, published between 1st of January 1995 and 31st of August 2019, on the prevalence of diabetes and pre-diabetes and their associated risk factors in Bangladesh. Only articles published in the English language articles were considered. Two authors independently selected studies. The quality of the articles was also assessed.ResultsOut of 996 potentially relevant studies, 26 population-based studies, which together involved a total of 80 775 individuals, were included in the meta-analysis. The pooled prevalence of diabetes in the general population was 7.8% (95% CI: 6.4–9.3). In a sample of 56 452 individuals, the pooled prevalence of pre-diabetes was 10.1% (95% CI: 6.7–14.0; 17 studies). The univariable meta-regression analyses showed that the prevalence of diabetes is associated with the factors: the year of study, age of patients and presence of hypertension. The prevalence of diabetes was significantly higher in urban areas compared with rural areas, while there was no significant gender difference.ConclusionsThis meta-analysis suggests a relatively high prevalence of pre-diabetes and diabetes in Bangladesh, with a significant difference between rural and urban areas. The main factors of diabetes include urbanisation, increasing age, hypertension and time period. Further research is needed to identify strategies for early detecting, prevention and treatment of people with diabetes in the population.PROSPERO registration numberCRD42019148205.

Background A number of primary studies in Ethiopia address the prevalence of birth asphyxia and the factors associated with it. However, variations were seen among those studies. The main aim of this systematic review and meta-analysis was carried out to estimate the pooled prevalence and explore the factors that contribute to birth asphyxia in Ethiopia. Methods Different search engines were used to search online databases. The databases include PubMed, HINARI, Cochrane Library and Google Scholar. Relevant grey literature was obtained through online searches. The funnel plot and Egger’s regression test were used to see publication bias, and the I-squared was applied to check the heterogeneity of the studies. Cross-sectional, case-control and cohort studies that were conducted in Ethiopia were also be included. The Joanna Briggs Institute checklist was used to assess the quality of the studies and was included in this systematic review. Data entry and statistical analysis were carried out using RevMan 5.4 software and Stata 14. Result After reviewing 1,125 studies, 26 studies fulfilling the inclusion criteria were included in the meta-analysis. The pooled prevalence of birth asphyxia in Ethiopia was 19.3%. In the Ethiopian context, the following risk factors were identified: Antepartum hemorrhage(OR: 4.7; 95% CI: 3.5, 6.1), premature rupture of membrane(OR: 4.0; 95% CI: 12.4, 6.6), primiparas(OR: 2.8; 95% CI: 1.9, 4.1), prolonged labor(OR: 4.2; 95% CI: 2.8, 6.6), maternal anaemia(OR: 5.1; 95% CI: 2.59, 9.94), low birth weight(OR = 5.6; 95%CI: 4.7,6.7), meconium stained amniotic fluid(OR: 5.6; 95% CI: 4.1, 7.5), abnormal presentation(OR = 5.7; 95% CI: 3.8, 8.3), preterm birth(OR = 4.1; 95% CI: 2.9, 5.8), residing in a rural area (OR: 2.7; 95% CI: 2.0, 3.5), caesarean delivery(OR = 4.4; 95% CI:3.1, 6.2), operative vaginal delivery(OR: 4.9; 95% CI: 3.5, 6.7), preeclampsia(OR = 3.9; 95% CI: 2.1, 7.4), tight nuchal cord OR: 3.43; 95% CI: 2.1, 5.6), chronic hypertension(OR = 2.5; 95% CI: 1.7, 3.8), and unable to write and read (OR = 4.2;95%CI: 1.7, 10.6). Conclusion According to the findings of this study, birth asphyxia is an unresolved public health problem in the Ethiopia. Therefore, the concerned body needs to pay attention to the above risk factors in order to decrease the country’s birth asphyxia.

Objective. Syphilis is one of the most imperative STIs, caused by the spirochete Treponema pallidum. During pregnancy it is associated with disastrous health outcomes in the newborn. In sub-Saharan Africa, study findings on the prevalence of syphilis among pregnant women are highly dispersed and inconsistent. The aim of the current review is to conduct a systematic review and meta-analysis of syphilis in sub-Saharan Africa among pregnant women. Design. Systematic review and meta-analysis. Data Sources. Databases including MEDLINE, PubMed, Cochrane Library, Google Scholar, and HINARI and reference lists of previous prevalence studies were systematically searched for relevant literature from January 1999 to November 2018. Results were presented in forest plot, tables, and figures. Random-effects model was used for the meta-analysis. For the purpose of this review, a case of syphilis was defined as positive treponemal or nontreponemal tests among pregnant women. Data Extraction. Our search gave a total of 262 citations from all searched databases. Of these, 44 studies fulfilling the inclusion criteria and comprising 175,546 subjects were finally included. Results. The pooled prevalence of syphilis among pregnant women in sub-Saharan Africa was 2.9% (95%CI: 2.4%-3.4%). East and Southern African regions had a higher syphilis prevalence among pregnant women (3.2%, 95% CI: 2.3%-4.2% and 3.6%, 95%CI: 2.0%-5.1%, respectively) than the sub-Saharan African pooled prevalence. The prevalence of syphilis among pregnant women in most parts of the region seemed to have decreased over the past 20 years except for the East African region. However, prevalence did not significantly differ by region and time period. Conclusion. This review showed a high prevalence of syphilis in sub-Saharan Africa among pregnant women. The evidence suggests strengthening the screening program during pregnancy as part of the care package during antenatal care visits. Programs focusing on primary prevention of syphilis in women should also be strengthened.

Background: Spasticity is a common sequela of stroke. The incidence of poststroke spasticity (PSS) has not been systematically reviewed in recent years, and some risk factors remain debated. This systematic review and meta-analysis was conducted to determine the prevalence and risk factors for PSS.Methods: We searched electronic databases (PubMed, Embase, Cochrane Library, CNKI, WANFANG and CBM) inception to May 12, 2020. Observational studies summarizing the incidence or risk factors for PSS were included. Only cohort studies were enrolled in meta-analysis. For risk factors examined in at least three different studies, we combined effects into odds ratios (OR) and 95% confidence intervals (CI).Results: One thousand four hundred sixty-seven studies were retrieved and 23 were involved in meta-analysis. The pooled prevalence of spasticity after stroke was 25.3% and that after the first-ever stroke was 26.7%. The incidence of spasticity after the first-ever stroke with paresis was 39.5%. The prevalence of disabling or severe spasticity (MAS ≥ 3) in stroke patients with paresis was 9.4% (95% CI 0.056–0.133), and severe spasticity was 10.3% (95% CI 0.058–0.149). Moderate to severe paresis (OR = 6.573, 95% CI 2.579–16.755, I2 = 0.0%), hemorrhagic stroke (OR = 1.879, 95% CI 1.418–2.490, I2 = 27.3%) and sensory disorder were risk factors for PSS.Conclusions: The incidence of PSS was significantly higher in stroke patients with paresis. Patients with moderate to severe paresis and sensory disorder should be closely followed up. The role of hemorrhagic stroke in predicting PSS remains to be further explored.

Background The rise in the global prevalence of diabetes, particularly among younger people, has led to an increase in the number of pregnant women with preexisting diabetes, many of whom have diabetes-related microvascular complications. We aimed to estimate the magnitude of the risks of adverse pregnancy outcomes or disease progression in this population. Methods and findings We undertook a systematic review and meta-analysis on maternal and perinatal complications in women with type 1 or 2 diabetic microvascular disease and the risk factors for worsening of microvascular disease in pregnancy using a prospective protocol (PROSPERO CRD42017076647). We searched major databases (January 1990 to July 2021) for relevant cohort studies. Study quality was assessed using the Newcastle–Ottawa Scale. We summarized the findings as odds ratios (ORs) with 95% confidence intervals (CIs) using random effects meta-analysis. We included 56 cohort studies involving 12,819 pregnant women with diabetes; 40 from Europe and 9 from North America. Pregnant women with diabetic nephropathy were at greater risk of preeclampsia (OR 10.76, CI 6.43 to 17.99, p < 0.001), early (<34 weeks) (OR 6.90, 95% CI 3.38 to 14.06, p < 0.001) and any preterm birth (OR 4.48, CI 3.40 to 5.92, p < 0.001), and cesarean section (OR 3.04, CI 1.24 to 7.47, p = 0.015); their babies were at increased risk of perinatal death (OR 2.26, CI 1.07 to 4.75, p = 0.032), congenital abnormality (OR 2.71, CI 1.58 to 4.66, p < 0.001), small for gestational age (OR 16.89, CI 7.07 to 40.37, p < 0.001), and admission to neonatal unit (OR 2.59, CI 1.72 to 3.90, p < 0.001) than those without nephropathy. Diabetic retinopathy was associated with any preterm birth (OR 1.67, CI 1.27 to 2.20, p < 0.001) and preeclampsia (OR 2.20, CI 1.57 to 3.10, p < 0.001) but not other complications. The risks of onset or worsening of retinopathy were increased in women who were nulliparous (OR 1.75, 95% CI 1.28 to 2.40, p < 0.001), smokers (OR 2.31, 95% CI 1.25 to 4.27, p = 0.008), with existing proliferative disease (OR 2.12, 95% CI 1.11 to 4.04, p = 0.022), and longer duration of diabetes (weighted mean difference: 4.51 years, 95% CI 2.26 to 6.76, p < 0.001) than those without the risk factors. The main limitations of this analysis are the heterogeneity of definition of retinopathy and nephropathy and the inclusion of women both with type 1 and type 2 diabetes. Conclusions In pregnant women with diabetes, presence of nephropathy and/or retinopathy appear to further increase the risks of maternal complications.

Abstract Background Despite the significant reductions in under-five mortality, campylobacteriosis has emerged as one of the most common causative agents of bacterial foodborne gastroenteritis in humans. We performed this systematic review and meta-analysis to estimate the pooled prevalence of Campylobacter species and associated risk factors among children less than 5 years of age in Ethiopia. Methods A systematic search was conducted on PubMed, Web of Science, EMBASE, Google Scholar and the Cochrane Library. All identified observational studies reporting the prevalence and determinants of diarrhea among children under 5 years of age in Ethiopia were included. Two authors independently extracted data and analyzed them using STATA Version 13 statistical software. A random-effects model was computed to estimate the pooled prevalence and the associations between determinant factors and campylobacteriosis. Results Out of 166 papers reviewed, 8 studies fulfilled the inclusion criteria and were included in the meta-analysis. The pooled prevalence of Campylobacter species among children under 5 years of age in Ethiopia was 10% (95% CI: 7, 13). Contact with domestic animals (OR: 3.2, 95% CI: 2.0, 5.1), illiterate mothers (OR: 2.1, 95% CI: 1.1, 3.8), consumption of animal products (OR: 1.7, 95% CI: 0.7, 4.5), and status of mothers’ personal hygiene (OR: 1.1, 95% CI: 0.7, 1.8) were significantly associated with the prevalence of Campylobacter species. Conclusion In our study, Campylobacter species among children under 5 years of age in Ethiopia were significantly high. Contact with domestic animals, illiterate mothers and consumption of animal products were significantly associated with prevalence of Campylobacter species

Objective Based on the epidemiologic findings of Covid-19 incidence; illness and mortality seem to be associated with metabolic risk factors. This systematic review and meta-analysis aimed to assess the association of metabolic risk factors and risk of Covid-19. Methods This study was designed according to PRISMA guidelines. Two independent researchers searched for the relevant studies using PubMed, Web of Science, Cochrane Library, and Scopus. The search terms developed focusing on two main roots of “Covid-19” and “metabolic risk factors”. All relevant observational, analytical studies, review articles, and a meta-analysis on the adult population were included in this meta-analysis. Meta-analysis was performed using the random effect model for pooling proportions to address heterogeneity among studies. Data were analyzed using STATA package version 11.2, (StataCorp, USA). Results Through a comprehensive systematic search in the targeted databases we found 1124 papers, after running the proses of refining, 13 studies were included in the present meta-analysis. The pooled prevalence of obesity in Covid-19 patients was 29% (95% CI: 14–47%). For Diabetes and Hypertension, these were 22% (95% CI: 12% 33%) and 32% (95% CI: 12% 56%), respectively. There was significant heterogeneity in the estimates of the three pooled prevalence without any significant small-study effects. Such warning points, to some extent, guide physicians and clinicians to better understand the importance of controlling co-morbid risk factors in prioritizing resource allocation and interventions. Conclusion The meta-analysis showed that hypertension is more prevalent than obesity and diabetes in patients with Covid-19 disease. The prevalence of co-morbid metabolic risk factors must be adopted for better management and priority settings of public health vaccination and other required interventions. The results may help to improve services delivery in COVID-19 patients, while helping to develop better policies for prevention and response to COVID-19 and its critical outcomes.

BACKGROUND Deficiency of iodine during pregnancy is associated with the increased rates of pregnancy loss, stillbirth, and increased perinatal and infant mortality and may lead to fetal iodine deficiency damaging the neurocognitive growth of the growing fetus. Even though, the implementation of nutrition interventions and other strategies across sub-Saharan African counties has resulted in the reduction of iodine deficiency prevalence, the prevalence of iodine deficiency remains high in many populations including pregnant mothers. OBJECTIVE The objectives of this review will be to estimate the pooled prevalence of iodine deficiency among pregnant mothers in Ethiopia. METHODS Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines will be followed for this systematic review and meta-analysis. The databases we will be; PUBMED, Cochrane Library, Google Scholar, CINAHL, and African Journals Online. Search terms we will use are “epidemiology” OR “prevalence” AND “iodine deficiency” OR “insufficient iodine intake” AND associated factors OR “determinant factors” AND “pregnant women” OR “pregnant mother” AND “Ethiopia”. Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI) will be used for critical appraisal of studies. Appropriate statistical tests will be conducted to quantify the heterogeneity between studies and the assessment of publication bias. We will check individual study influence analysis and also conduct subgroup analysis. STATA version 15 will be used for statistical analysis. RESULTS This systematic review started in September 2020. The literature search of the 5 databases revealed 483 papers. We are currently at the screening stage. CONCLUSIONS The systematic review and meta-analysis will provide the pooled prevalence of iodine deficiency among pregnant mothers in Ethiopia. The finding of this study will be helpful to design appropriate preventive and health promotion strategies for the reduction of iodine deficiency; related maternal and fetal morbidity and mortality.

Abstract Background Neural tube defects are common congenital anomalies that result from early malformation in the development of the spinal cord and brain. It is related to substantial mortality, morbidity, disability, and psychological and economic costs. The aim of this review is to determine the pooled birth prevalence of neural tube defects and associated risk factors in Africa. Methods The first outcome of this review was the pooled birth prevalence of the neural tube defects and the second outcome was the pooled measure of association between neural tube defects and associated risk factors in Africa. We systematically searched PubMed, PubMed Central, Joanna Briggs Institute, Google Scopus, Cochrane Library, African Journals Online, Web of Science, Science Direct, Google Scholar, and Medline databases. The heterogeneity of studies was assessed using the Cochrane Q test statistic, I2 test statistic, and, visually, using Forest and Galbraith’s plots. A random-effect model was applied to get the pooled birth prevalence of neural tube defects. Subgroup, sensitivity, meta-regression, time-trend, and meta-cumulative analyses were undertaken. The fixed-effect model was used to analyze the association between neural tube defects and associated risk factors. Results Forty-three studies with a total of 6086,384 participants were included in this systematic review and meta-analysis. The pooled birth prevalence of the neural tube defects was 21.42 (95% CI (Confidence Interval): 19.29, 23.56) per 10,000 births. A high pooled birth prevalence of neural tube defects was detected in Algeria 75 (95% CI: 64.98, 85.02), Ethiopia 61.43 (95% CI: 46.70, 76.16), Eritrea 39 (95% CI: 32.88, 45.12), and Nigeria 32.77 (95% CI: 21.94, 43.59) per 10,000 births. The prevalence of neural tube defects has increased over time. Taking folic acid during early pregnancy, consanguineous marriage, male sex, and substance abuse during pregnancy were assessed and none of them was significant. Conclusions The pooled birth prevalence of neural tube defects in Africa was found to be high. The risk factors evaluated were not found significant.

Abstract Background Existing evidence indicates that the risk of obstetric and perinatal outcomes is higher in women with coronavirus infection. outbreaks suggest that pregnant women and their fetuses are particularly susceptible to poor outcomes. However, there is little known about pregnancy related complications and co-morbidity in this group of women. Therefore, this, systematic review and meta-analysis performed in order to find out whether COVID-19 may cause different manifestations and outcomes in antepartum and postpartum period or not.Methods We searched databases, including Medline (PubMed), Embase, Scopus, Web of sciences, Cochrane library, Ovid and CINHAL to retrieve all articles reporting the prevalence of maternal and neonatal complications, in addition clinical manifestations, in pregnant women with COVID 19 that published with English language from January to April 2020. Results 11 studies with total 177 pregnant women included in this systematic review.Results show that the pooled prevalence of neonatal mortality, lower birth weight, stillbirth, premature birth, and intrauterine fetal distress in women with COVID 19 were 4% (95% Cl: 1 - 9%), 21% (95% Cl: 11 – 31%), 2% (95% Cl: 1 - 6%), 28% (95% Cl: 12 - 44%), and 15% (95% Cl: 4 - 26%); respectively. Also the pooled prevalence of fever, cough, diarrhea and dyspnea were 56% (95% Cl: 30 - 83%), 30% (95% Cl: 21 - 39%), 9% (95% Cl: 2 - 16%), and 3% (95% Cl: 1 - 6%) in the pregnant women with COVID-19.Conclusion According to this systematic review and meta-analysis, the pregnant women with COVID-19 with or without pneumonia, are at a higher risk of pre-eclampsia, preterm birth, miscarriage and cesarean delivery. Furthermore, the risk of LBW and intrauterine fetal distress seems increased in neonates.
